Abstract
The utility model relates to an adjusting device for an impact rack of an impact crusher. The adjusting device comprises a threaded sleeve, a spherical washer, a spring, a gasket and a pull rod, and is characterized in that a spring adjusting bolt and an inner nut sleeve are arranged between the spherical washer and the spring; and the inner nut sleeve is sleeved outside the spring adjusting bolt. When the adjusting device is used, the pressed degree of the spring is adjusted through the spring adjusting bolt firstly; during the use process of the adjusting device, when the pull rod is required to be adjusted inwards or outwards, the spring adjusting bolt can adjust the spring simultaneously to always keep a certain pressing degree of the spring, without causing the problem of easy failure of the spring; and at the same time, the manufacturing cost is lowered, the adjustment is convenient, the disassembly and the assembly are simple and convenient, and the using effect is better.
Description
Technical field
The utility model relates to impact breaker.
Background technology
Domestic counterattack frame adjusting device generally has two kinds at present.A kind of is the device that the spring compression degree can not be adjusted, and like Fig. 1, broken the going up of PF1214 counterattack strikeed back broken adjustment.Another kind is that the spring compression degree is controlled separately, and the gap adjustment of counterattack frame is again independent control.Like Fig. 2, the adjustment of the broken counterattack frame down of PF1315 counterattack.First kind shortcoming is that spring compression can not be adjusted, and second kind structural disadvantages is to make more complicated, regulates cumbersomely, and manufacturing cost is higher.
Summary of the invention
[0003] to the technical problem of above-mentioned prior art, the utility model proposes a kind of impact breaker simple in structure counterattack frame adjusting device.
The concrete technical scheme of the utility model is following:
A kind of impact breaker counterattack frame adjusting device comprises swivel nut, spheric washer, spring, packing ring and pull bar, and its characteristics are, between spheric washer and spring, are provided with spring and regulate bolt and inner nut cover; Said inner nut cover is enclosed within spring and regulates the bolt outside.
Duty of the utility model and beneficial effect:
Regulate the compressing degree that bolt is adjusted spring through spring earlier during use, in use pull bar needs inward, when regulating outward; Spring is regulated bolt adjustment together simultaneously, can keep the certain compressing degree of spring all the time, can not cause the problem that is prone to inefficacy like the spring that is easy to generate among Fig. 1; Reduced manufacturing cost simultaneously; Be convenient to regulate, remove and install all comparatively easyly, result of use is better.
Description of drawings
Fig. 1 is existing a kind of impact breaker counterattack shelf structure sketch map.
Fig. 2 is existing another kind of impact breaker counterattack shelf structure sketch map.
Fig. 3 is the impact breaker counterattack shelf structure sketch map of the utility model.
Among the figure: the 1-swivel nut; The 2-spheric washer; The 3-spring is regulated bolt; 4-inner nut cover; The 5-spring; The 6-packing ring; The 7-pull bar.
The specific embodiment
As shown in Figure 3, a kind of impact breaker counterattack frame adjusting device comprises swivel nut 1, spheric washer 2, spring 5, packing ring 6 and pull bar 7, between spheric washer 2 and spring 5, is provided with spring and regulates bolt 3 and inner nut cover 4; Said inner nut cover 4 is enclosed within spring and regulates bolt 3 outsides.
Regulate the compressing degree that bolt is adjusted spring through spring earlier during use, in use pull bar needs inward, when regulating outward; Spring is regulated bolt adjustment together simultaneously, can keep the certain compressing degree of spring all the time, can not cause the problem that is prone to inefficacy like the spring that is easy to generate among Fig. 1; Reduced manufacturing cost simultaneously; Be convenient to regulate, remove and install all comparatively easyly, result of use is better.
